IPC: B61L29/00
Filed: 2010-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a railroad-crossing obstacle detector and an obstacle detection method that prevent misdetection of an obstacle due to effects of weather such as rain.SOLUTION: The level of reflected waves obtained by transmitting radio waves to a detection area is collated with one or more reference patterns, specified on the basis of weather conditions such as light rain and heavy rain, so as to select and determine the reference pattern fitting to the actual weather condition. As a result of the comparison, an obstacle is detected on the basis of the matched reference pattern, thereby preventing false detection of an obstacle due to diffused reflection of radio waves caused by weather such as rain.
